Paper bag construction

INC., 01 BROOKLYN, NEW YORK, A. CORPORATION ,OF NEW YORK PAPER nae consrnoorrou Application filed January 6, 1931. Serial No. 506,845.

This invention relates to paper bags, envelopes and similar receptacles, and constitutes a further development of and improvement upon the paper receptacles described and shown in the application of Maurice Rosenfeld Serial No. 377,932, filed July 13, 1929.

The principal object of the present invention is the production of a bag of a construction such that it can be produced by the machine and process disclosed in my'prior application Serial No. 316,462, filed/November 1, 1928, and at the same time provide means for readily carrying the bag.

A feature of the bag disclosed in the present application which distinguishes it from the prior art and from the bag disclosed in the Rosenfeld application above referred to, is that the finger opening, is carried, is spaced from the line of paste which is used to secure the overlapping ortions of the paper web in forming the ag.

A further feature of the invention is a bag which can be made by the process and machine disclosed in said oppe application and which is provided with a tab or a plurality of tabs by which the mouth of the bag may be closed.

With these and other objects in view the invention comprises the novel and improved bag construction hereinafter described and particularly "pointed out in the claims, refer-' ence being had to the accompanying drawing in which Figure 1 is a broken view of a bag illus trating one form of invention:

Figure 2 is a similar view showing the reverse side of the bag;

Figures 3. 4 and 5 are modifications; and

Figure 6 is a perspective view of the bag shown in Figure 5 and serves to illustrate how the bag is formed from a web of paper without waste.

Referring to Figure 1, the bag comprises a 1 front wall 1 and a rear wall 2. The web of paper forming the bag is overlapped at 3 along the rear wall and lines of paste 4 and 5 serve to secure the web together to thereby form a bag-tube from which separate bags may be cut by well-known processes of bag by which the bag manufacture, but preferably by the process and machine disclosed in said Poppe application. When the bag is made by said process and machine, it is preferably formed with a closing flap 6 which is a prolongation of the rear wall of the bag tube and which flap may be folded over on to the front wall to close the mouth of the bag.

To provide a construction which may be convenient to carry, the front and rear walls of the bag are provided with registering openings indicated at 7 through which a finger may be inserted in carrying the bag. These openings are preferably in circular form and may be quickly and easily made after the bags are completed and piled in stacks, by means of an ordinary paper drill, this method of making the finger holes hav-. ing been described in said Rosenfeld application.

The flap 6 is provided with a tongue 8 which is also similar to the tongue described in said Rosenfeld application. The present invention differs, however, from the construction described in said application in that the overlap or seam is of such width that the tongue 8 is entirely within the paste lines of the bag. The finger holes 7 are also entirely within the paste lines. This construction has the advantage in speed of manufacture. It is also possible with the present construction to drill the finger holes in the bags immediately after they come from the machine and before the paste has had a chance to completely dry and, due to the fact that the openone side of the bag and both the tongue 8 and the holes 7 are spaced from the paste line.

The Figure 4 construction is similar to that shown in Figure l insofar as the general formation of the bag is concerned, but the prolongation 6 serves as a handle for carrying the bag and other means are provided for closing the mouth of the bag. In this constructionthe overlap atathe rear wall of the bag is of greater extent than in the Figure 1 construction, and there are two lines of paste 4 and 5, but, in addition, the front wall .of the bag is provided with a tab 9 which is adapted to be inserted through a slit 10 which passes throu h both plies of the overlap. The opening likewise passes through both plies of the overlap and between the lines of paste. The tab 9 and slit 10 are also between the paste lines.

The construction shown in Figure 5 diflers from that shown in Figure 4 in that two tabs 13 and 14 are provided in the front wall of the bag and these are adapted to be inserted through slits 11 and 12 in the portion 6.

Figure 6 illustrates in perspective a bag in which the bottom is shown partly opened out to give a better idea of the manner in which such a bag may be formedwithout waste. It will be noted that the tabs 13 and 14 (which are shown in reversed position due to the fact that in Figure 6 the rear wall of the bag is uppermost) fit the depressions 15 and 16 in the flap which closes the bottom of the bag. The same will be true of the Figure 4 construction, the tab Qfitting into a corresponding depression in the bottom flap.

' What I claim for my invention is 1. A paper bag formed of a web overlapped to form a seam, a line of paste along the edge of the seam and a finger opening through the bag walls spaced from the paste A line, and a closing flap havingslits extending inwardly from the margin thereon and wholly within the seam, forming a tongue arranged to be passed through said opening.

2. bag formed of a web overlapped near the central longitudinal portion of one wall thereof to form a seam, lines of paste adjacent the ed es of the seam and a finger opening throug said walls entirelywithin the lines of paste.

3. A bag formed of a web overlapped near the central longitudinal portion of one wall thereof to form a seam, lines of paste adjacent the edges of the seam, a finger opening through said walls entirely withln the lines of paste and a closing flap having slits within the 1paste lines and extending inwardly from t e margin of the flap, forming a tongue arranged to be passed through said opening.
